I can't scan as a normal user on Mandriva 2006!

On Mandriva 2006 iscan will not start when run by a normal user. When invoked from the command line, the following error message appears:

"Could not send command to scanner. Check the scanner's status."

[Solution]
You can fix this by editing /etc/udev/rules.d/70-iscan.rules. This requires root privileges.

(before) SUBSYSTEM!="usb_device", GOTO="iscan_rules_end"
(after) SUBSYSTEM!="usb", GOTO="iscan_rules_end"

We have confirmed this behavior and workaround with the following setup.

[Relevant driver]
Image Scan! for Linux 2.2.x

[Relevant distribution]
Mandriva 2006

[Relevant Scanner]
ES-H300
GT-2500

Note: Although not confirmed, the same behavior is expected with Image Scan! for Linux 2.1.x.
